Then it works.=============Today, I setup a new windows 10 1809 system + Apache 2.4.38 and found a new problem that cannot loaded imagick extension. But after I installed Visual C++ Redistributable for Visual Studio 2015 from MS site, all work ok. And the operation `ADD LoadFile "/yourImageMagickPath/bin/CORE_RL_Magick++_.dll" in httpd.conf` is not need.

Unfortunately the Windows binaries downloaded from the Imagemagick website did not work with PHP 7. It seems that they used Visual C++ 2013 to compile imagemagick while PHP used Visual C++ 2015. There is another build of imagemagick which worked with PHP 7 here: http://windows.php.net/downloads/PECL/deps/
